Description

Technical Field

[0001] The invention relates to the technical field of plant extraction preprocessing, in particular to a plant extraction preprocessing device. Background Art

[0002] In order to better transfer the target substance in the mixture to another solvent, it is often necessary for the mixture to be in full contact with the solvent. Therefore, the mixture is often crushed to increase the contact area between the mixture and the solvent. In order to further improve the utilization efficiency and production efficiency, the crushed material (usually plants) is generally pressed to better discharge the liquid mixture, so that it can be more fully mixed with the solvent and reduce the adverse effects of solid materials on extraction. However, when existing pre-processing devices crush and press plants, it is often difficult to balance the processing efficiency of the two processes of crushing and pressing. That is, crushing is generally simpler and faster, while pressing takes a relatively long time. In particular, as the number of single pressed materials increases, the corresponding pressing difficulty will increase, and at the same time, the utilization rate and pressing efficiency will be reduced, highlighting its shortcomings.

Therefore, when the swing rod 8 reciprocates back and forth with the No. 2 support shaft 5 as the axis, the two accordion protective covers 11 can be compressed and stretched by using the ball 9 and the slider 10, so that the opening at the top of the swing plate 3 can be blocked to prevent the material from entering and causing pollution and blockage. The front and rear ends of the lower cylinder 1 are respectively fixed with a horizontal No. 3 support shaft 12, and the front and rear parts are each penetrated by a horizontal lower sliding groove 13. The two No. 3 support shafts 12 are respectively coaxially rotatably connected with a No. 3 gear 14, and the No. 3 gear 14 is meshed with the No. 1 gear 7. The two lower sliding grooves 13 are slidably connected with a horizontal sliding box 15. The lower cylinder 1 and the sliding box 15 are installed with a discharge part 16, and a feeding part 17 is installed on the upper part.

[0017] The discharge part 16 includes a screen 18, a No. 1 drainage trough 19, a No. 1 drainage pipe 20, a support rod 21, a rack 22, a baffle 23, a lower support plate 24, a screen 25, a hinge shaft 241, a rib 251, a No. 2 drainage trough 26, a No. 2 drainage pipe 27, and a support leg 28.

The left and right parts of the slide box 15 are respectively fixed with two horizontal baffles 23. The lower left and right parts of the lower cylinder 1 are respectively installed with horizontal lower support plates 24, and the inner wall The lower left and right parts are respectively fixed with leakage plates 25, and the front and rear ends of the opposite parts of the two lower support plates 24 are respectively fixed with horizontal hinge shafts 241, and the two lower support plates 24 are hinged with the lower cylinder 1 through the hinge shafts 241, and the bottom ends can contact the outer circumferential wall of the support rod 21. The two leakage plates 25 are inclined to gather toward the middle and lower part, and a plurality of vertical ribs 251 are fixed between the lower cylinder 1. The leakage plates 25 inclined toward the middle and lower part can not only make it more convenient for juice to pass through them, but also can make juice flow into the lower cylinder 1. The hole enters the No. 2 drainage groove 26 and can increase the contact area with the material to facilitate pressing, while the rib 251 can improve the structural strength of the leakage plate 25 during pressing and reduce deformation. A horizontal No. 2 drainage groove 26 is fixed between the bottom of the two leakage plates 25 and the lower cylinder 1, and a vertical No. 2 drainage pipe 27 is fixed in the middle of the bottom end of the two No. 2 drainage grooves 26. The No. 2 drainage pipe 27 is connected to the No. 2 drainage groove 26, and vertical support legs 28 are fixed at the left and right ends of the lower cylinder 1.

[0018] The feeding part 17 includes an upper cylinder 29, a funnel 30, a support frame 31, an upper support plate 32, a double-axis motor 33, a swing arm 34, a rotating frame 35, a screw dragon 36, a crushing shaft 37, a crushing knife 38, a fourth gear 39, and an inner gear ring 40. A vertical upper cylinder 29 is fixed to the top of the lower cylinder 1, a vertical funnel 30 is fixed to the upper part of the inner wall of the upper cylinder 29, and a horizontal support frame 31 is fixed to the bottom inner wall. A horizontal upper support plate 32 is fixed between the bottom outer wall of the funnel 30 and the inner wall of the upper cylinder 29. A vertical double-axis motor 33 is fixed to the top of the middle part of the support frame 31, and a downward-inclined swing arm 34 is fixed to the bottom rotating shaft of the double-axis motor 33. , and a horizontal rotating frame 35 is fixed to the bottom of the upper rotating shaft, the swing arm 34 is rotatably connected to the swing rod 8, and a screw dragon 36 is coaxially fixed to the upper part of the upper rotating shaft of the double-axis motor 33, and the screw dragon 36 is gap-plugged with the bottom of the funnel 30, and the parts of the rotating frame 35 away from the rotating shaft of the double-axis motor 33 are rotatably connected with multiple vertical crushing shafts 37, and each of the crushing shafts 37 is respectively fixed with a horizontal crushing knife 38 at the upper and lower parts, and the crushing knives 38 at the upper and lower parts of the crushing shaft 37 are cross-staggered, and a fourth gear 39 is coaxially fixed to the upper end, and a horizontal inner gear ring 40 is fixed to the bottom end of the upper support plate 32, and the inner gear ring 40 is meshed with each fourth gear 39.

[0019] The dual-axis motor 33 is connected to an external power supply and a controller. When the dual-axis motor 33 is powered on and rotated, it can drive the rotating frame 35, the auger 36 and the swing arm 34 to rotate. When the rotating frame 35 rotates, it can drive the crushing shaft 37 to move circumferentially, and the engagement of the fourth gear 39 and the inner gear ring 40 can be used to rotate the crushing shaft 37. When the dual-axis motor 33 rotates, it can drive the swing arm 34 to rotate, so that the swing rod 8 can swing circumferentially. During the circumferential swinging process, the swing rod 8 can be hinged with the second support shaft 5 to make the swing plate 3 swing back and forth left and right. During the left and right swinging process, the upper part of the swing plate 3 can partially overlap with the top projection of the two guide plates 2, that is, the guide plate 2 can be used to block the gap between the upper part of the swing plate 3 and the lower cylinder 1 to avoid the deviation of the material falling to the other side when the swing plate 3 is used to guide the material to be discharged. During the reciprocating left and right swinging process, the sliding box 15 can be made to reciprocate left and right by the No. 1 gear 7, the No. 3 gear 14 and the rack 22. During the reciprocating left and right sliding process, the sliding box 15 can block the lower sliding groove 13 with itself and the baffle 23, thereby preventing the material from flowing out of the lower sliding groove 13 and causing waste. When the sliding box 15 reciprocates left and right to the leftmost part, the support rod 21 on the left part can be separated from the contact with the lower support plate 24 on the left part of the lower cylinder 1, so that the lower support plate 24 can rotate downward under the action of gravity to achieve a vertical state. When the sliding box 15 reciprocates left and right to the rightmost part, the support rod 21 on the right part can be separated from the contact with the lower support plate 24 on the right part of the lower cylinder 1, so that the lower support plate 24 can rotate downward under the action of gravity to achieve a vertical state. The No. 1 drainage pipe 20 and the No. 2 drainage pipe 27 are connected to the external liquid collection device through a hose.

[0020] The working principle of the present invention is as follows: when in use, the material is intermittently or continuously put into the hopper 30 through the conveying equipment, and then the double-axis motor 33 is controlled to rotate slowly. At this time, the double-axis motor 33 drives the auger 36, the rotating frame 35 and the swing arm 34 to rotate slowly, and the slow rotation of the auger 36 in the hopper 30 can make the material enter the bottom of the upper cylinder 29 relatively slowly, and the slow rotation of the rotating frame 35 can make the crushing shaft 37 move circumferentially relatively quickly, and at the same time, the crushing shaft 37 can rotate rapidly under the meshing of the inner gear ring 40 and the fourth gear 39, so that the falling material can be quickly crushed, and the crushed material continues to fall into the upper cylinder 29 and is in the guide Under the guidance of the plate 2, they converge to the lower middle part of the lower cylinder 1, and the swing arm 34 will make the swing plate 3 swing back and forth left and right through the swing rod 8 during the circumferential swinging process, and the swing plate 3 will make the sliding box 15 slide back and forth left and right through the No. 1 gear 7, the No. 3 gear 14 and the rack 22 during the reciprocating swinging of the left and right. Specifically, when the swing plate 3 tilts to the lower right, the sliding box 15 is close to the leaking plate 25 on the left part of the lower cylinder 1, and when the swing plate 3 tilts to the lower left, the sliding box 15 is close to the leaking plate 25 on the right part of the lower cylinder 1, and when the sliding box 15 moves to the leftmost and rightmost sides, it can make the adjacent lower support plate 24 break away from the contact with the support rod 21 and rotate downward to present a vertical state. Therefore, through the above description The following process can be achieved by the above description. When the swing plate 3 tilts to the lower right, the crushed material can be guided by the swing plate 3 to fall into the larger space between the right side of the sliding box 15 and the leak plate 25 on the right side of the lower cylinder 1, and at this time, the lower support plate 24 adjacent to the leak plate 25 is in a horizontal state under the support of the support rod 21, so it can well receive the material. Subsequently, when the swing plate 3 tilts to the lower left, the crushed material can be guided by the swing plate 3 to fall into the larger space between the left side of the sliding box 15 and the leak plate 25 on the left side of the lower cylinder 1, and at this time, the lower support plate 24 adjacent to the leak plate 25 is in a horizontal state under the support of the support rod 21, so it can well receive the material. Correspondingly, at this time The sliding box 15 slides to the right and gradually slides to the rear end, during which the material on the top of the lower support plate 24 on its right side in the previous stage can be squeezed, and finally the lower support plate 24 loses the support of the support rod 21 and rotates downward to discharge the residue. As the sliding box 15 slides to the left, the support rod 21 will support the lower support plate 24 again to restore the horizontal state, and squeeze the material on the left side of the sliding box 15, and the cycle is repeated. The juice squeezed during the squeezing process can pass through the leak plate 25 and the leak screen 18 into the No. 1 drain trough 19 and the No. 2 drain trough 26, and finally be discharged from the No. 1 drain pipe 20 and the No. 2 drain pipe 27, thus realizing the crushing and squeezing functions.

[0021] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.

The part of the rotating frame (35) away from the rotating shaft of the double-shaft motor (33) is rotatably connected with a plurality of vertical crushing shafts (37). The upper and lower parts of each crushing shaft (37) are respectively fixed with a horizontal crushing knife (38). The crushing knives (38) of the upper and lower parts of the crushing shaft (37) are arranged in a cross-staggered manner, and a fourth gear (39) is coaxially fixed on the upper end. A horizontal inner gear ring (40) is fixed at the bottom end of the upper support plate (32). The inner gear ring (40) is meshed with each fourth gear (39). ; 2. A pre-processing device for plant extraction according to claim 1, characterized in that: The double-axis motor (33) is externally connected to a power source and a controller. When the double-axis motor (33) is powered on and rotated, it can drive the rotating frame (35), the auger (36) and the swing arm (34) to rotate. When the rotating frame (35) rotates, it can drive the crushing shaft (37) to move circumferentially, and can use the meshing of the fourth gear (39) and the inner gear ring (40) to rotate the crushing shaft (37). When the double-axis motor (33) rotates, it can drive the swing arm (34) to rotate, and can cause the swing rod (8) to swing circumferentially. During the circumferential swinging process, the swing rod (8) can cause the swing plate (3) to swing back and forth by hinged connection with the second support shaft (5). During the left and right swinging process, the upper part of the swing plate (3) can partially overlap with the top projection of the two guide plates (2). During the left and right swinging process, the swing plate (3) can be moved back and forth by the first gear (7). The third gear (14) and the rack (22) can make the sliding box (15) swing back and forth. During the process of sliding back and forth, the sliding box (15) can block the lower sliding groove (13) with itself and the baffle (23). When the sliding box (15) slides back and forth to the leftmost part, the support rod (21) on the left part can be separated from the contact with the lower support plate (24) on the left part of the lower cylinder (1), so that the lower support plate (24) rotates downward under the action of gravity to achieve a vertical state. When the sliding box (15) slides back and forth to the rightmost part, the support rod (21) on the right part can be separated from the contact with the lower support plate (24) on the right part of the lower cylinder (1), so that the lower support plate (24) rotates downward under the action of gravity to achieve a vertical state. The first drainage pipe (20) and the second drainage pipe (27) are connected to an external liquid collection device through a hose.
